The frame-work A is and may be of suitable shape to support the bearings for the working parts, the upper part of the framework broken off and not herein shown, as well as the parts omitted from the upper end of the die-bed spindle B, being substantially the same as in United States Patent No. 374,894. The die-bed spindle B, its bearings B, the toggle-links D D, center-pin D lever A, rod iv, connected to it and moved by the die-bed spindle, the guide 11:, (see Figs. 1 and 3,) the spring L03 upon the said rod, the guide 3, (see Fig. 4,) the carriage O fitted to slide thereon, the trimmer-lever C the cam 12, (see Figs. 24 and 26,) the lever 1), moved by it, and the trimming-shaft B are also the same as in the said patent, where like letters are employed to represent like parts. The main or power shaft A having a fast pulley A driven bya belt in any usual manner, has fast upon it at the inner side of the said pulley (see Fig. 5) a toothed pinion A and at its opposite end the said shaft has fast to it a pinion A The pinion A engages and drives continuously a wheel or toothed gear A normally loose on a shaft A, extended across the frame-work, and having secured to it at its opposite end a pinion A", (see Figs. 5 and 7,) the said pinion in turn engaging and rotating constantly a toothed gear A normally loose on a camshaft A", extended across the machine. The pinion A engages a wheel or toothed gear B normally loose upon the trimmer-shaft B.

The gearing so far described is kept in motion continuously from the power-shaft A and its pinion A and at intervals the wheel or toothed gear A is made to actuate,.through a suitable clutch, a sleeve B (see Fig. 7,) and the wheels or gears A and B are made, through suitable clutches, to engage and rotate intermittingly the shafts on which they normally run loose.

The cam-shaft A at its opposite end, or at the left-hand side of the machine, has a brakewheel A which is embraced by a brake-shoe A (see Fig. 4,) faced with leather or equivalent material to come directly in contact with the said wheel A flthe shank of the brake-shoe being extended into the hub of a bracket A, (see Fig. 5,) bolted to the framework, the said shoe being acted upon by a strong spring, as A so that the said brakeshoe is forced against the wheel A to prevent the rotation of the cam-shaft through momentum. The opposite end of the trimmer-shaft B has secured to it a weighted crank B having a pin B, which enters a shoe B (see Fig. 6,) which travels in a slot of the pivoted trimming-lever 0 which lever at its upper end embraces a block extended from one side of the carriage, G which is fitted to slide upon the guide 3, the said carriage in practice having connected to it the usual chain, (not shown,) which is'employed to rotate in one and then in the opposite direction the usual trimming-lever and devices, (not shown,) but which in practice are mounted loosely upon the upper end of the die-bed spindle, the said trimming-shaft and the devices engaged by it to rotate the trimming-leverbeing all substantially as common in United States Patent No. 374,894, while the trimming devices carried by the said trimming-lever at the upper end of the die-bed spindle are and may be in practice the same'as in United States Patent No. 166,765.

Each of the three wheels or toothed gears A A B are provided at their inner side with a chamber for the reception of a clutch device by which the said wheel or gear A may be made to rotate the sleeve 3, and the wheels or gears A and B be made to rotate at times the shafts upon which they are IIO mounted loosely and at other times to leave the said sleeve and shaft at rest.

Referring to Fig. 7, which shows the toothed gear A, it will be seen that the chamber at the side of the gear receives loosely a clutch, consisting,essentially, of a loose collar 0, (see Fig. 7,) and shown separately in Figs. 10 to 12. This collar has two like cam projections O and a series of fingers C, the opposing sides of which are concaved, so as to hold between them a series of friction-rolls C the ends of the said fingers and the said rolls being represented in Fig. 4 by breaking away part of the outer face of the wheel or gear A.

The collar at its rear side (see Figs. 10 and 11) has a circular groove, as OZin which are secured two like pins 2, upon each of which is hooked one end of a like spiral spring 4, the free end of each spiral spring not reaching quite to the pin 2 which holds the other spiral spring, so'that a small space is left, as shown in Fig. 11, at the free end of each spiral spring 4 for the reception of a stud, as 5, projecting from a flange or collar 0 (shown in section in Fig. 7 and separately in Fig. 7%) the said collar being keyed to the sleeve 13 it having, as shown, integral with it a cam or eccentric B, which is surrounded by the strap-like end of a connecting rod or link N, which at its front end is jointed to the center pin 1) of the usual toggle-links D D, employed for raising and lowering the diebed spindle.

The sleeve B has fixed to it between its ends a hub, as C the periphery of which (see Fig. 4) is provided with a series of cam-faces orinclines, againstwhich rest the rollers (Jacarried between the fingers O of the collar 0, the said rollers being all moved down the said inclines and from biting contact with the inner side of the chamber in the wheel or gear A whenever the collar 0 (see Figs. to 12) is arrested by a clutch-controlling device, (shown as an elbow-lever E the said lever having an arm D "(see Figs. 2 and 37,) the springs 4 (see Fig. 11.) at such time being compressed; but when the collar 0 is not held by the said clutch-controlling device the springs 4 are free to turn the said collar about the said hub 0 the said collar at such time moving the said rollers up the inclines of the hub G and causing the rollers O to be engaged between the said hub and the wheel or gear A so that the said wheel or gear, which is moved continuously, takes the sleeve 13 with it, thus rotating the cam or eccentric B and moving the die-bed spindle. Normally, the springs 4, acting upon the studs 5, projecting from the collar 0, turn the collar 0 slightly forward about the hub 0 or in the direction of the arrow, Fig. 4, thus carrying the friction-rolls 0 up the inclined surface of the said hub. The springs 4 are not, however, permitted to act and move the collar as described except when the clutch-controlling device or lever B is turned away from the path of rotation of the projection (I of the collar C, this movement of the clutch-controlling device in the operation of the machine taking place at different times, as will be described. v The sleeve B carrying the eccentric B, has suitably keyed to it a friction-wheel B having two surfaces of unequal diameter, as best shown in Figs. 5,7, 8, and 9, each surface being acted upon by a suitable friction-brake, as B or 13 carried, as herein shown, by a single brake-lever B held in place on a stud B in a stand B the said friction-brakes acting upon the surface of the said frictionhub merely to prevent the rotation of the sleeve 13 when not being moved positively by the friction-clutch mechanism before described.

In operation the sleeve B" must be rotated quickly for one full rotation and then stopped, as when the die-bed spindle is being raised and lowered to nail a heel upon the shoe, the shoe being held upon a last carried by a lastearrying spindle common to United States Patent No. 374,894. The die-bed spindle having been lowered, it remains down long enough to permit the usual top-lift carrier common to the said Patent No. 374,894 to bring a top lift into position between the usual top-lift plate of the nail-box and the heel, after which the sleeve B is again started and moved for half a rotation to lift the die-bed spindle B to blind a top lift upon the nails of the heel, and then the sleeve stops with the spindle elevated long enough to permit the usual trimming mechanism common to the Patent No. 166,765 to come into operation to trim the heel, after which the said sleeve 13 is again started quickly and turned. half a rotation to break the toggle-joint of and lower the die-bed spindle for the removal of the shoe. The sleeve B remains at rest as long as the controlling device or lever B acts against one of the projections O and arrests the rotation of the collar O.

The arm D of the clutch-controlling lever has two toes 17 18, to be described. The clutch-controlling lever B is acted upon by a spring D (see Figs. 2 and 4,) connected to the arm D of the said lever, so that the upturnedrear end of the said lever normally stands in position to be struck by a projection 0 of the collar 0 in its rotation.

IIS

The clutch mechanism between the wheels or gears A and I) and the cam and trimming shafts are alike, so we will specifically describe but one of the said clutches, designatin g, however, the like parts of both clutches by the same letters. The cam-shaft A" and the trimmenshaft B have fixed to them at the right-hand side of the machine like hubs a, (see Figs. 1, 16, 19, and 20,) each hub having at its inner side two pins to, substantially like the pins 4, before described, the pins a entering an annular groove a (see Fig. 14) at the outer side of a loose hub a having a single projection to and being provided with a series of fingers, as a, between which are placed a series of friction-rolls a. Each annular groove a referred to receives in it two spiral springs a, which are held therein substantially as described of the spiral springs 4. The cam-shaft A has a fixed hub a (see Figs. 13, 17, and 18,) provided with a series of cam-surfaces or inclines, on which the fricand will turn the said treadle so that, through the link -d, (see Fig. 2,) jointed to it and to an arm cl, projecting from a hub d mounted loosely upon a stud (1 the said arm will be lifted suzfliciently to strike against the arm 1) and turn the controlling device B upon .its fulcrum The camshaft A" ,near the .center of its length is enlarged in diameter, as at A ,.,(s,ee Fig. 523,) and is grooved longitudinally to receive .a locking device a (shown as a key,) which is secured atone end (see Fig. 2.4-) toa collared, having an annular groove a nvhich receives :a yoke-shaped stud a, (see Fig. 7,.) pivotedupon the innerend of a lever C03, in turn pivoted at a, (see Fig. 4,) and having oo-operating with it a holding device a, by which-the said lever maybe held in either oneof two positions, one position of the said lever, .as shown in .Figs. 7 and-2.4, beingthat to holdthe said locking device a pushed in, so as to lock the cam b to the shaft A as when 'the top liftis being blinded. on the heel, the'other positionof the lever (L13 being that wherein its outer end is moved to the right from Fig. 1, such movement withdrawing the said locking device, freeing the said cam b from the shaft A Thelocking device (L -T9- ferred to'hastwo projections, as d a The enlarged, part A of the cam-shaft A is surrounded loosely by the top-lift carrier-movingcam b, it having at its inner side a camgroove, asllG, (see Fig. 26,) which receives in it a'roller or other stud at the lower. end of a lever 1), common to United StatesPatent No. 374,894, the upper end of the said lever engaging and reciprocating the usual slide-bar of thetop-lift carrier, as in the latterpatent.

The cam I) referred to has fixed to it by a bolt 55, (see Figs. '2 and 24,) so as to form a partof it, a cam-plate hfihaving three projections 1O 12 13, two spaces It 15, and a rest 16.

Viewing Fig. 26 it will be seen that the cam 11 has a hole 52, and in Figs. 27 and 29 it will be seen that a projection 53 of the cam-plate b has a threaded hole 5e. )Vhen the cam b and cam-plate b are mounted in position on the cam-shaft, a bolt 55 (shown by dotted line, Fig. 7, and in section, Fig. 8) is used to enter the said holes 52 and 54: to thus rigidly connect together the said cam b and the camplate b, so that when the cam is locked and restraine fr m otation the .cam plate w also remain at rest. The toe 17 of the arm D is nearest the front of the machine and. lies immediately over the auxiliary cam I), while the toe l8 stands in the path of the cam-plate b The hub of the auxiliary cam 12 is loose on the enlarged part A of the cam-shaf A at the lef -hand s de of hem-n11- plate 12 hen the machine is adjusted into position to be started to nail a heel upon a shoe, th toe 1 stand n the rest 1 v(see E 2,) and if the machine is to be operated to nail heel upon theslioe and to then blind the top lift thereon and trim the heel, the projection a of the locking device a will .be'moved to enter thegroot eor key-seat in the interior of the top-lift cam has in Figs. 7 and 24, thus locking it fast to the cam-shaft, and the projection a of the said locking device will stand in the notch 12 .of the said pain-plate b and a portion of the said -projection a will also stand in the semicircular recess b atthe left-hand side of the ring-cam I), employed to start the trimming. In this condition of the parts the operator, by putting his foot upon the treadle, will turn the controlling device or lever B as described, to release collar C and .cause the sleeve Bi to he started to raise the die-bed spindle to nail the =heelupon the shoe. As the cam plate b is started ,in the direction of the arrow thereon in 2 the projection 10 willengage the toe 18 just before the cam projection G on the collar or hub C arrives opposite the end ofthe said controlling device B The can1 10,acting on the toe 18, holds up the i ner end D of the lever-controlling device 13 so that the upturned end thereof is kept outof'the way of one of the projections O on the hub C,

thus permitting the sleeve B 9, carrying the eccentric, to travelfor more than half arotation; but as soon as-the toe ISarrivesjatthe rearend of the projectionlO, the heelhaving been nailed upon theshoe, the toe-l8 drops, permitting the controlling device 13 to be turned by the spring ;D and place the upturned rear end of-the said device B in the path of movement ofthe said, projections O thus arresting therotation of the hub O and thesaid sleeve withthe die-bed spindlelowcred, thesaid spindle being retainedlowered while the. top-lift cam 1) acts upon the lever b to 'move forward the top-lift slide-bar carrier having a top lift common to Patent No. 374,894, andplace the top lift between the usual top-lift plate and the endv ofthe heel, the toe 18 at such time restingin the first space 14 of the cam; but as soon as the top lift is in position tobe blinded upon the heel the projection 12 of the cam-plate b strikes the toe 18 and turns the lever B to remove its rear end from that one of the projections (3*, and hub C then engaged by it, thus releasing the hub, so that it places the rolls carried by it in position to be caught by the wheel A and again rotate. the sleeve B to lift the die-bed spindle B and the usual nailbox at the upper end thereof to blind the top lift upon the end of the nails previously driven into the heel. The acting portion of the projection 12 is of such length that it passes from under the toe 18 and lets the end D of the lever B drop, thus placing the upturned end thereof in position to be engaged by one of the said projections (1 in the rotation of the hub and sleeve; but just before the said sleeve B completes a halfrotation, the second space 15 of the cam-plate 1) comes under the said toe 18, the said toe remaining in the said space for a sufficient time during the rotation of the cam-plate b to permit the usual trimming mechanism referred to and carried in usual manner, and the upper end of the die-bed spindle is moved to trim the heel, which done the projection 13 of the cam-plate b again strikes the toe 18 to effect the release of the hub or collar 0 to again start the sleeve B to eifect the final lowering of the die-bed spindle, the toe 18 by the time the said spindle is lowered dropping into the rest 16. This completes one rotation of the cam-plate I), and during its rotation, as will be understood, the cam projection 12 has automatically moved the lever B to release the hub O to lift the die-bed spindle, and has then permitted the end D of the said lever to drop, thus again placing the upturned end thereof in position to arrest the hub 0 just as the sleeve B completed a half-rotation, thus leaving the diebed spindle in elevated position while the trimming mechanism operated to trim the heel, which done the third projection 13 came into operation, moved the lever B to again release thehub O and permit the sleeve B to make another half-revolution, it at such time effecting the lowering of the spindle.

The hub of the auxiliary cam b has mounted upon it loosely the cam-ring'b which starts the trimming, and the right-hand side of the said cam-ring is held up snugly against the left-hand side of the auxiliary cam Z) by means of a gib-plate 6, (see Figs. and 31,) attached to the said auxiliary cam by a screw 6', a segmental lip of the said gib-plate entering an annular groove 6 of the said camring. In practice there is sufficient friction between the auxiliary cam b and the cam: ring D to prevent the cam-ring from being accidentally pushed ahead in the direction of the rotation of the auxiliary cam, as when the roll f at the lower end of the lever f is opposite the long inclined part of the projection f of the trimming cam-ring D it rotating in the direction of the arrow thereon in Fig. 32. The trimming cam-ring h is carried forward in unison with the auxiliary cam b while the machine is operating to nail a heel and to then put a top lift thereon and to trim the heel by the left-hand corner of the projection a of the locking device a it resting against a shoulder of the recess at the right-hand side of the said cam-ring b thestarting-point of the trimming cam projection f being located nearly midway between. the two projections 10 12 of the cam-plate b. The projection 56 of the auxiliary cam b (see Fig. 30) is of substantially the shape and size and stands just to the left of the projection 12 of the cam-plate b but with the starting end of the projection of the cam 19 a little in front of the projection 12. The projection on the auxiliary cam is provided to at times act upon the toe 17 of the lever B; but when the heel being applied is to have a top lift blinded upon it the projection 56 of the auxiliary cam is unable to strike the toe 17 and turn the lever 13 for the proj tion 12 acts upon the toe 18 and turns the said lever B just before the projection 56 of the auxiliary cam arrives in position to act upon the toe 17.

In the operation of the machine, as the projection f of the cam-ring Z7 arrives opposite the roll f at thelower end of the lever f',pivoted at f it vibrates the said lever, throwing its upper end to the right, viewing the machine from its front, the said end being forked, (see dotted lines, Fig. 5) and embracing a suitable stud f (see Fig. 2) upon the sliderod f The slide-rod f has attached to it, near its right-hand end, (see Fig. 35,) a yoke f which by a bolt f is fixed to a second slide-rod f extending through suitable bearings and surrounded at its end at the lefthand side of the machine by a strong spiral spring f which normally acts against a fixed collar f on the said rod f and against one of the bearings 200, in which the said rod f slides, to thus throw the rod f to the left or in a direction opposite that in which itis moved by the said projection f The rod f has securely fixed to its right'hand end an arm f, provided at its outer end with a plunger f, normally thrown out by a spring. The toothed gear B normally loose on the trimming-shaft, receives loosely within its chambered hub one of the loose hubs a before described, (see Figs. 1 and 16,) as having a projection Before the lever f is moved by the trimming cam projection f to start the trimming-lever C in usual manner the plungerf stands in contact with the projection a of the said hub 60 as shown in Fig. 1; but as the lever f is moved by the trimming cam projection f the arm f 12 is moved laterally from contact with the projection a of the loose hub a thus permitting the friction-rolls carried by the said hub to be engaged by the interior of the gear B causing the said gear to start in rotation the trimming-shaft B; but as soon as the heel or smallest part of the cam proj ection) of the trimming cam-ring arrives opposite the roller at the lower end of the lever f the spring f on the slide-rod f imme- 7 to'the left, thus again placing diately acts to throw.the said rod and arm f the plunger f 13 n the hue of travel of the projection a of the loose hub a so that the said hub is stopped and the friction-rolls are moved inwardly to release the gear B by the time the trimmingshaft has made one complete revolution. Tlie arm g, which co-operates with a like loose hub a as described, loose on the cam-shaft A to arrest the rotation of the said hub a when it is desired to effect the release of the gear A from the cam-shaft A and leave it at rest, is connected to the right-hand end of a slide-rod g, surrounded at its left-hand end by a strong spiral spring which is placed between a shoulder g on the said rod and one of the bearings for the said red, the spring 9 normally acting to keep the end of the arm 9 1n ,theline of movement of the projection a of the loose hub (F. The movement of the cam-shaft A should commence just as the die-bed spindle B arrives in its most elevated position, as when the heel has been nailed to plied to the pin D the shoe, and it is at this time that the arm 9 must be moved to release the loose hub a and permit the gear A to be operatively clutched to the cam-shaft A". To do this I have apconnecting the links of the toggleoint, a short link 71 which is fitted over a pin it of an arm 7&2 of the hub (Z loose on the stud d, before described, the said hub havmga cam projection 7L3, (see Figs. 1 and 22,).wh1ch acts upon a roller M at the upper end of a short lever 71 pivoted at 45, the lower end of the said lever being forked and embracing a cross-pin of the slide-rod q, as described, of the lever and its connection w th the rod f, the cam 7L3 thus moving the slide-rod g to remove the arm g from the proection a of the hub (L This cam 7L3, acting as described, moves the rod q to the right, placlng the arm 9 out of the path of movement of the projection a at each rise of the (he-bed spindle B, and permitting the said arnr g to move into the range of the said proect on a at each descent of the said die-bed sp ndle; but at the second descent of the said spindle, when the arm 9 is moved inwardly, the projection a of the loose hub (L2 has completed but about half a rotation. Therefore at such time the said projectiouo does not strike the arm 9, for the latter is quickly moved again to the right by the second rise of the die-bed spindle, as when the top lift is,

being blinded on. This second movement of the slide-rod g is not one which effects any operation of the machine as so far described, but is a mere incident of the construction of the parts, and the said bar is made to derive its motion from the part of the machine referred to, thus saving the addition of complex devices to the machine, as would otherwise be necessary.

The hub of the top-lift cam b has a notch 46, Fig. 25, in line with the projection (L of the locking device or key a before described.

One of the bearings 47 in which the camshaft A rotates is provided with a locking dog or device 48, (herein shown as a sliding spring-pressed block.) This locking-dog 48 is pressed back against its spring by the righthand end of the locking device a and is so kept pressed back so long as the machine is to be used to nail heels and blind top lifts thereon.

\Vhen the machine is to be used to nail a heel, blind top lift, and trim the heel, then the sleeve B is to have a full revolution without intermediate stopping and then two halfrevolutions in succession between the commencement and completion of each heel; but when the heel is only to be nailed through and through and trimmed, I have provided means whereby the said sleeve 13 has two half-revolutions in successionone when the spindle is lifted to nail the heel, and the other when the spindle is lowered. To effect this different movement of the die-bed spindle, the lever (013 Will be turned in the direction to move the locking device a to the.left on the cam-shaft away from the front of the machine, such movement of the said locking device removing its end from the locking-dog 48, permitting the said dog to enter the notch in the hub of the top-lift cam Z) to lock it to the bearing 47, in which the camshaft rotates, so that the said cam Z) cannot rotate, the same movement of the locking device a to the left withdrawing the projection (L18 from the seat or groove of the hub of the cam 19, thus releasing the said cam from the camshaft A and at the same time the projection a of the locking device a is drawn out from the key-seat in the cam-plate far enough to enter the slot 40 in the trimming cam-rin g I), so that the right-hand corner of the said projection a will come into the re cess 50 at the left-hand side of the said ring, viewing Fig. 1, such change of position of the projection a with relation to the cam-ringb temporarily releasing the ring, and permitting it to make a substantially half-rotation of the hub on the auxiliar cam b, so as to place the projection f, for starting the trimming-lever, at about one hundred and twenty degrees behind the projection 56 of the said auxiliary cam b". Now that the top-lift cam b and the cam-plate b are at rest, the projection on the auxiliary cam 11 performs the duty heretofore performed by the projection 2 of the cam-plate b that is, it lifts the inner end D of the lever B to effect the release ofthe collar or hub O to start the sleeve B to effect a half-rotation thereof and lower the spindle, the projection of the auxiliary cam'b at such time acting upon the toe 17.

\Vhen simply nailing through the heel and trimming it, the operator, with his foot on the treadle E, lifts the inner end of the lever B as before described, to effect the starting of the sleeve B but the said sleeve for this work is permitted to complete but a half-rotation to thus lift the die-bed spindle, and as IIO ITS?

soon as the said spindle has been lifted and the heel nailed to the shoe the cam portion of the trimming cam-ring Z1 strikes the roll f of the lever f, and effects, as before described, the starting of the trimming-lever to trim the heel; and the trimming operation having been completed the cam projection 56 on the auxiliary cam again acts on the toe 1.7 to lift the inner end of the arm D of the lever 13 to effect the starting of the sleeve 13 for its second half-rotation to lower the spindle when the machine is automatically stopped. In this way it will be seen that very much time is saved, and that were it notfor the auxiliary cam and the change of position of the trimming-cam with relation to the projection 13, which is made to lower the die-bed spindle, very much time would be lost.

\Vhen the locking device a is again re-,

turned into the position shown in Fig. 23, the corner of the cam projection a nearest the cam 11 passes through the opening or slot 6.) of the cam-ring.
